Monster VoIP was established to distribute superior voice quality and maximized uptime to customers from here in L.A. to New York to Washington, D.C. to Houston to Dallas to Chicago and beyond, while delivering unparalleled service and customer satisfaction. We started by setting up data centers in Las Vegas, New York, Dallas, and Minnesota to ensure geo-redundancy, with all endpoints multi-registered at all four facilities. (This is just a fancy way of saying that multiple locations means you can expect amazing voice quality and unparalleled business phone uptime.) We then made sure to offer a complete suite of communication tools in one platform. This means you and your team only have to learn our easy-to-use user interface for all of your communication efforts. To make good on our customer satisfaction promise, we then decided to provide personalized setup and ongoing 24/7/365 support to every business VoIP customer that walks through our (virtual) doors.
